Haswell - Voltage settings

[mikel23]

Hi,

Need insight with this, I recently upgraded to haswell and well all is fine - just that bios is default except for some bootup changes but cpu voltage etc... are default. now coming from an OC'd rig before this I always set my voltages at what the system needs to run and frankly I'm at a lost trying to set the voltages with haswell - should I leave the bios voltages on default or set them to the correct voltages (BTW I've tried searching the web for a guide but no answer to my particular system)

My specs:

CPU: i5 4430
MB: Asrock B85-HDS
Ram: G-Skills ripjaws 4x2
GFX: Sapphire 7770 dual x
HDD: 350gb Seagate (OS) 1TB Samsung F3 (files)
PSU: Atec VP-550
Case: Antec One S3

any input would be greatly appreciated

The motherboard tries to automatically find the best voltage. I would try both and see which is more stable with a stress test.
Try to change it from SPEC Mode to FIXED Mode in the BIOS.

thanks for replying cars12345, I have tried looking up info on what default voltage my cpu needs but haven'e come across anything in the web and also I don;t know which settings to change in the BIOS except for RAM voltage, which is set to 1.5V - manufacturer spec (I also have my ram on XMP 1.3) do you have any info or links that show how to manually set the volatages on my mobo?

thanks
